Abstract
Background an Aim: parapsoriasis is a rare chronic
idiopathic dermatosis which commonly manifests with round or oval scaling and
itching erythematosus plaques on trunk and extremities. Considering the size of
the lesions, parapsoriasis is divided into two groups: small plaque and large
plaque. Study of demographic characteristics of this disease may help to
identify the high risk groups who are more susceptible to cutaneous lymphoma
with high mortality as well as proper allocation of health service resources.
Methods: In this retrospective cross-sectional study,
affected parapsoriasis patients whom were referred to Razi Hospital in Tehran between
April 2003 to March 2009 were studied. Three hundred and twenty patients were
investigated for variables: age, sex, place of residence, location of the lesions
and clinical subgroups according to the histopathology reports.
Results: 53.4% of patients were female. The disease was most
commonly observed in age group of 20 to 50 years and the mean age of the patients
was 43.3 years. Eighty-five percent of the patients were inhabitant of Tehran
province. 88.1% of patients had large plaque lesions and 11.9% had small plaque
lesions. The most common sites of lesions were on the trunk (53.4%) followed
by the extremities (38.7%).
Conclusion: Based on these findings, it was determined that
parapsoriasis most commonly affects middle-aged women. Involvement of trunks and
extremities were most commonly observed. Large plaque type was the most common
type.
